If `alpha` is the degree of dissociation of `na_(2)SO_(4)` the vant of Hoff's factor (i) used for calculating the molecular mass is-

A

`1+alpha`

B

`1-alpha`

C

`1+alpha`

D

`1-2alpha`.

Text Solution

Verified by Experts

The correct Answer is:
C
`Ns_(2)SO_(4)hArr2Na^(+)+SO_(4^(2-))`
`{:(1,0,0),(1-alpha,2alpha,alpha):}`
Vant Hoff factor (i) `=(1-alpha+2alpha+alpha)/(1)=1+2alpha`
